Final answer:
Zofran, which contains the active ingredient ondansetron, is the preferred drug for treating chemotherapy-induced nausea and vomiting. It is administered intravenously and is a controlled substance due to its potential risks.
Step-by-step explanation:
The preferred drug in the treatment of chemotherapy-induced nausea and vomiting (CINV) is Zofran, which contains the active ingredient ondansetron. Zofran functions effectively to prevent nausea and is often used in conjunction with cancer treatments such as chemotherapy and radiation therapy. This medication can be administered intravenously, as shown in the vial of Zofran 4 mg for injection. It is important to note that Zofran is a controlled substance, indicating its use is regulated due to potential risks associated with its use.
Other medications, like phenergan, can also assist with managing nausea, and are part of a broader strategy to alleviate various symptoms associated with cancer therapy, including pain and dry mouth. While certain other medications can interfere with cell division and treat different infections, it is Zofran that is specifically recognized for its antiemetic properties in the context of CINV.
